Are we all just assuming these searches are from people who regret their votes and hoped to be able to change it?
I double checked my ballot before submitting it, with full knowledge that irrevocability is the price of anonymity. Nevertheless, I might use similar search terms if I was curious how many other voters, possibly in other states or with different political alignments, had written about regretting their votes. Or, perhaps, ... if I was doing research for a post-election article about the topic.
That's a great point. The Trump team tried to get all voter information from all states in 2020. Ostensibly to verify voter fraud. But this data was probably used to create such voter suppression systems as Eagle AI.
